Which tool is primarily used for pushing back cuticles?

The orange wood stick is primarily used for pushing back cuticles due to its design and material. This tool is typically made of a soft wood, allowing it to gently push back the cuticles without causing damage to the delicate skin or nail matrix. Its narrow tip can easily access the areas around the nail, making it perfect for this specific task.

The cuticle nipper, while a useful tool for trimming excess cuticle, is not appropriate for pushing cuticles back as it could cut the skin or cause irritation. A buffer is designed to smooth and shine the nail surface, and a nail file is intended for shaping the edges of the nails. Neither of these tools serves the purpose of pushing back cuticles, reinforcing the orange wood stick's role as the ideal choice.
